thereafter fill the car, the device being so constructed that the casemay not be opened until after the car has been emptied.

The invention is illustrated and described in a specific embodiment towhich, however, it is not to be restricted. The right is reserved tomake such changes or alterations as the actual seduction to practice maysuggest, in so far as such changes or alterations are compatible inspirit with the annexed claims.

The same numerals of reference designate the same parts throughout theseveral figures of drawings, wherein 1 Figure l is a view in sideelevation of a portion of the front end of a mine car showing theinvention applied thereto.

Fig. 2 is a section on the line 22 of Fig. 1.

Fig. 3 is a view similar to Fig. 2 but showing the device in openposition.

Fig. 4 is a perspective view of the mova'ble plate comprising part ofthe device and in which there is formed a pocket for the miners check.

Referring to the drawings, the invention is illustrated as applied to amine car, the front wall 1 of the body of which is shown. In this frontwall there is formed a pocket 2' and in the back of the pocket a hole 3which opens on the inside of the front wall.

Directly above the pocket 2 there is mounted on the outside of the wall1 a plate 4 preferably of rectangular shape, this plate being formedwith flanges 5, extending laterally from its upper edge and two sideedges.

Designed to cooperate with the plate 4 there is a second plate 6 whichon the bottom edge is formed with a lug 7 designed to stand in thepocket 2 when the plate 6 is set against the plate 4 with the flanges ofthe latter plate overlapping the edges of the former plate. On the innerface of the plate 6 there is formed a pocket 8 of such shape andthickness as to receive the usual miners tag and the plate 6 is slottedas indicated at 9, this slot 9 communicating with the pocket 8, so thatthe tag may be inserted through this slot to drop in the pocket 8.

An ear 10 is formed on the plate 6 at the upper edge and at the top ofthe pocket 8, so as to assist in withdrawing the plate 6 from engagementbetween the flanges 5 oi the plate 4, in opening the device in a mannerhereinafter described.

Plate 6 is connected with an L-shapcd bar the longer leg 11 of whichhangs against the front wall 1 of the car on the inside of the latterand the shorter leg 19. of which passes through the hole 3 and isattached in the lug 7. A plate 13 is mounted on the back of the wall 1adjacent the hole 3 and acts as a guard for the hole to prevent itsenlargement by the L-shaped bar when the latter is shifted to effect theopening of the device.

The plate 6 stands normally against the plate 4 surrounded on its edgesby the flanges 5 of the latter, the longer leg 11 of the L-shaped barthen hanging against the inside face of the wall 1. In such a positionof the several parts the miner fills the car on which the device isattached when the longerleg of the L-shaped bar is hidden in the coalwithin the car and is precluded thereby from any movement. The minerthen inserts his check through the slot 9 and it falls into the pocket 8from which it may not be removed except by shifting the plate 6 frombetween the flanges of the plate 4 which is prevented as long as themovement of the L-shaped bar is precluded. The car is then transportedto the dump for unloading and when empty the device may be opened byswinging the longer leg 11 of the L-shaped bar away from the inner faceof the front wall 1. This operation swings the plate 6 downwardly andaway from the plate 4, the pocket 8 housing the lug 7 permitting suchdownward movement of the plate 6 as well as such downward movement ofthe lug 7 and leg 12 of the L-shaped bar. Of course, if the olates 4 and6 should be so snugly engagec as to endanger the breaking of either theplate 6 or the lug 7 in separating the two plates by the raising of theleg 11 of the bar, the ear 10 may be employed to initially separate theplates 4 and 6.

IVith the plate 6 swung away from the plate a, as shown in Fig. 3,access is had to the pocket 8 and the check contained therein.

An opening M is formed in the plate 6 at a point that will permit thereading through it of the number of the tag held in the pocket 8.

The invention having been described, what is claimed as new and usefulis:

1. In a check lock for mine cars, a plate attached to one wall of thecar on the outside thereof, the said plate being formed with flanges, asecond plate designed to lie against the first said plate so that it issur rounded on the edges by the flanges of the latter, the second saidplate being formed with a pocket designed to receive a check of thecharacter described, and means connected with the second said plate andcarried interior to the car, the said means holding the second saidplate in position within the flanges ot' the first said plate and beingoperable to swing the plates apart only when the car is empty.

2. In a device of the kind described, the combination with a mine car,of a plate formed with a pocket therein, and means carried interior tothe car and supporting the plate which is exterior to the car, the saidmeans being adapted to swing the plate away from the side of the car orinto close contact with the latter and being operable only when the caris empty.

3. In a device of the kind described, the combination with a mine car,of a plate mounted on the exterior wall thereof and provided withflanges on a part of its perimeter, a second plate formed with a pocketand engageable between the flanges of the first said plate, the secondsaid plate being formed with a lug, the wall of the car adjacent thefirst said plate'being formed with a pocket in which the lug rests, andan L shaped bar having one leg connected with the lug and the other legdisposed within the car so that when the said latter leg hangs againstthe inside wall of the car the two plates may be held together, theswinging of the said leg away from the said inside wall of the carseparating the two plates for the removal when the car is empty of acheck inclosed within the Pocket.

4:. In a device of the kind described, the combination with a mine car,of a plate mounted on the exterior wall thereof and provided withflanges on a part of its periphery, a second plate formed with a pocketand engageable between the flanges of the first said plate, the secondsaid plate having a lug, the wall of the car being formed with a pocketin which the lug rests, and an L- shaped bar having one leg connectedwith the lug and passing through the wall of the car and the other legdepending within the car against the inside wall thereof whereby the twoplates are held together to inclose the pocket of the first said platewhen the car is full, the second said plate being formed with an ear onthat edge opposite the lug and further formed with a slot to permittheinsertion therethrough of a tag to be carried in the pocket, that leg ofthe L- shaped member hanging within the car being adapted for swingingmovement away from the side wall thereof to separate the two plates toexpose the pocket in the second said plate, the ear on said second saidplate providing means for the initial separation of the plates Intestimony whereof I afiix my signature.

NED WILLIAMS.
